JOURNAL-BOX. 7

Specification Letters Patent.

Patented Dec. 16, 1919.

Application filed March 3, 1919. Serial No. 280,230.

To all whom it may concern:

Be it known that I, WILLIAM M. WILSON, a citizen of the United States, residing at Emporia, in the county .of Lyon and State of Kansas, have invented certain new and useful Improvements in Journal-Boxes, of which the following is a specification.

This invention relates to journal boxes and more particularly for an attachment therefor, the primary object being to provide a device which will take up the wear caused by the lateral thrusts of the parts mounted in the bearing.

Th invention is primarily designed for use upon locomotive journal boxes but it will be obvious that the attachment will be readily adapted for all machinery where the journal box wears because of the continual pressure exerted by the lateral thrusts of the parts mounted in the bearing.

The invention further aims to provide a detachable plate adapted to be mounted on the bearing so that it may be quickly removed and displaced when desired so that as one plate is worn a new one may be substituted.

A further object of this invention is the production of a device of this character which is simple in construction but durable and well adapted to withstand the rough usage to which devices of this character are ordinarily subjected.

For a full description of the invention and the advantages and merits thereof, reference is to be had to the following description and accompanying drawings, in whic Figure 1 is a front elevation of a journal box showing my invention applied thereto,

Fig. 2 is an edge elevation of the same,

Fig. 3 is a section taken on the line 33 of Fig. 1.

Fig/4 is a horizontal section taken on the line 4l of Fig. 1.

Fig. 5 is a front elevation of the journal box showing the plate removed.

Fig. 6 is a perspective view of the removable plate,

Fig. 7 is a fragmentary top plan view,

Referring to the drawings, wherein is illustrated the preferred form of my invention, in which like characters of reference indicate like or corresponding parts throughout the several views, the journal box is of the usual construction and has its front face as shown particularly in Figs. 4 and 5 provided with parallel grooves 2 and 3 which extend vertically at opposite sides of the journalopening 4:. The grooves 2 and 3* are undercut at their longitudinal edges and they terminate at points slightly spacedfrom'the bottom of the bearing, so that the shoulders 5 are provided at the ends of the grooves. These shoulders are also undercut as indicated by the dotted lines in Fig. 5. The upper ends of the grooves are enlarged by beveling the inner wall as indicated at 6 to facilitate the insertion of the removabl plate 7 Removable plates consist of a substantially rectangular plate shown to advantage in Fig. 6 having a central vertical slot 8 which provides parallel side portions 9 and 10 adapted for reception in the grooves 2 and 3 respectively. These side portions have their longitudinal edges beveled so that they may readily fit into the undercut grooves 2 and 3 and in this manner a dovetailed joint is provided for maintaining the plate in position on the front face of the boxing. The plate 7 is considerably thicker than the depth of the grooves 2 and 3 so that when the plate is mounted in position it extends outwardly from the base 11 of the boxing and thus fills the space occasioned by the wear from the lateral thrusts of the parts supported in the boxing.

The plate is also slightly tapered so that it is thicker at its upper end than at its lower end so that a wedge like action occurs when the device is in position.

By referring to Fig. 6 is will be noted that the parallel portions 9 and 10 which fit in the grooves 2 and 3 are larger at their upper ends than at their lower ends, thereby permitting them to snugly fit within the enlarged upper portions of the grooves 2 and 3 and act as wedges to hold the plate firmly in position. v

The foregoing description and accompanying drawing have reference to what might b considered to be the approved or preferred form of my invention. I desire it to be understood that I may make such changes in construction, combination and arr. mgement of parts, materials, dimensions, et cetera, as may prove expedient and fall within the scope of the appended claim.

Having thus fully described my invention what I claim as new and desire to secure by Letters Patent, is

An attachment for journal boxes, comprising the combination with a boxing, the

front face ofwhich is provided with vertical parallel grooves, one groove on each side of the journal opening and spaced therefrom by a substantial portion of the boxing immediately surrounding the journal opening, each side of this substantial portion forming one Wall of the vertical parallel grooves and being beveled above the journal openings, and terminating abruptly adjacent the upper face of said boxing to consolidate said grooves, and a slotted plate engaging the grooved face of said boxing and having a recess therein provided and conforming to the contour of the substantial portion surrounding the journal opening, said substantial portion being adapted to fit into and engage the recess of the slotted plate so that the beveled sides of the former Will co-act with the corresponding Wall of the recess for Wedging the plates to the boxing in substantially locked relation.

In testimony whereof I afliX my signature in presence of two Witnesses.
